Was in a big display frame until recently. Signed to Louise with Mark Cavendish autograph. I bought this without any providence or authentication so cannot provide any to the buyer but I believe it to be genuine. Its a new jersey not race worn. Italian size L-4-50 I assume that's large. Have taken some photos with measurements if that helps. Cavendish rode for omega quick step 2013 to 2015 so it's from around that date. Has the rainbow collar and sleeves for world champion.
